Cadbury’s “Not Just a Cadbury Ad” campaign using AI deepfake technology reached 140+ million people during Diwali, representing one of the most ambitious applications of AI personalization in advertising history. I’ve been analyzing this campaign closely, and what emerges is a case study in how AI can create hyper-personalized experiences at unprecedented scale.
The 32% brand engagement increase and 21% online sentiment boost demonstrate the potential of AI to transform traditional advertising while respecting cultural sensitivities.
The Campaign Concept That Broke the Mold
The campaign featured 2,500+ personalized Shah Rukh Khan endorsements, each tailored to different customer segments and regions. Instead of generic celebrity endorsements, Cadbury used AI deepfake technology to create personalized messages that resonated with individual viewers.
The concept was brilliantly simple: Shah Rukh Khan appearing to speak directly to viewers, acknowledging their specific interests, regional preferences, and personal connections to Cadbury products. The AI made each endorsement feel personal and authentic, even though it was created at massive scale.
The Technical Innovation Behind the Scale
The deepfake technology represented a significant technical achievement:
facial recognition integration that analyzed viewer profiles and preferences, regional language adaptation with automatic translation and cultural adaptation, personalization algorithms using machine learning to match viewer interests with product messaging, real-time generation that created personalized videos on-demand, and quality assurance systems that ensured deepfake quality met broadcast standards.
This technical foundation enabled the campaign to reach 140 million people with personalized experiences, something previously impossible with traditional advertising methods.
The Cultural Sensitivity Challenge
Creating personalized content for Diwali, one of India’s most important cultural festivals, required careful attention to cultural nuances like different Diwali traditions across India, 22 official languages plus numerous dialects, appropriate symbols and traditions for each region, and connecting Cadbury products with individual family traditions.
The AI system was trained on extensive cultural data to ensure appropriateness and relevance across different demographic groups.
The Engagement Metrics That Defied Expectations
The campaign’s success metrics were remarkable with a 32% brand engagement increase that was significantly higher than traditional advertising, a 21% online sentiment boost that drove positive conversations about Cadbury and the campaign, massive reach to 140+ million people exposed to personalized content, high shareability through social media sharing of personalized endorsements, and conversion impact that increased sales during the Diwali period.
These results demonstrate AI’s ability to create more engaging and effective advertising than traditional mass-market approaches.
The Ethical Considerations Addressed
The campaign navigated significant ethical challenges:
- Deepfake Transparency: Clear disclosure of AI involvement
- Consent and Privacy: Respecting user data and privacy preferences
- Cultural Appropriateness: Ensuring content aligned with cultural values
- Misinformation Prevention: Avoiding any misleading claims or representations
Cadbury’s approach set a new standard for responsible AI use in advertising.

This production scale represents a fundamental shift in advertising capabilities.
